Two weeks ago, in the early morning hours of July 12, hell descended upon the village of Donki Dereisa in South Darfur. Shortly before sunrise, Fatima Ibrahim, a 28-year old woman of noble features and simple ways, awoke from her sleep to the deafening sound of exploding ordnance falling from the sky and the rattle of automatic weapons fire. As she emerged from her mud hut with her ten year old daughter, she saw fires blazing all around and scores of heavily armed men on horseback attacking the village from every direction.
